A concept for coupling lensed fiber arrays to photonic optical chips in the submicrometer range by using metal deformation is presented. Fine-tuning is possible despite already secured positions between the parts due to precisely chosen step-by-step deformations in the constructions. The smallest fine-tuning step of 0.1 um is measured using laser support adjustment. The system is packaged and can be temperature controlled. At a constant chip temperature of 22 degrees C, the package is successfully tested at an ambient temperature range of 0 to 60 degrees C.
